Max Gekk f1fde0cc22 [SPARK-31490][SQL][TESTS] Benchmark conversions to/from Java 8 datetime types ... ### What changes were proposed in this pull request? - Add benchmark cases for **parallelizing** `java.time.LocalDate` and `java.time.Instant` column values. - Add benchmark cases for **collecting** `java.time.LocalDate` and `java.time.Instant` column values. ### Why are the changes needed? - To detect perf regression in the future - To compare parallelization/collection of Java 8 date-time types with Java 7 date-time types `java.sql.Date` & `java.sql.Timestamp`. ### Does this PR introduce any user-facing change? No ### How was this patch tested?
